Wire electric-discharge machining device and wire-electrode removing device configured to remove cut wire-electrode

摘要

A wire electric-discharge machining device and wire-electrode removing device are provided. The wire-electric discharge machining device includes a wire-electrode cutting unit that is arranged in a running path of a wire electrode, and a removing unit configured to remove the wire electrode cut by the wire-electrode cutting unit from the running path. The removing unit includes a wire-electrode guide unit that is arranged below the wire-electrode cutting unit and includes a through hole configured to receive a wire-electrode guide pipe and further configured to receive the wire electrode in the running path. The wire-electrode guide unit is configured to guide an end of the wire electrode to a position outside the running path, with the cut wire electrode provided in the through hole, by rotationally moving about a wire-electrode guide shaft.

1. A wire electric-discharge machining device comprising:
a wire-electrode cutting unit that is arranged in a running path of a wire electrode, the wire-electrode cutting unit being configured to cut the wire electrode; and a removing unit configured to remove the wire electrode cut by the wire-electrode cutting unit from the running path, wherein the removing unit includes:
a wire-electrode guide unit that is arranged below the wire-electrode cutting unit in the running path of the wire electrode, the wire-electrode guide unit comprising a through hole configured to receive a wire-electrode guide pipe during a wire connection operation to connect the electrode wire to rollers and further configured to receive the wire electrode in the running path when electric-discharge machining using the wire electrode, the wire-electrode guide unit being configured to guide an end of the wire electrode, formed by a cutting operation of the wire-electrode cutting unit, to a position outside the running path, with the cut wire electrode provided in the through hole, by rotationally moving about a wire-electrode guide shaft when removing the wire electrode cut by the wire-electrode cutting unit;a winding shaft unit configured to wind and remove the cut wire electrode guided by the wire-electrode guide; anda collection member that collects the wound and removed wire electrode.
